Abstract
A landmine detection prototype based the detection of residual explosives in soils was tested in 1996 on a landmine field located at DRES. The minefield included 25 buried mines, 25 empty sites and one with a TNT block buried in the soil. In order to evaluate the efficiency of the system, the detection of explosives (TNT and RDX) was performed on these 51 sites. The detector could not detect the presence of mines due to the low concentration of explosives on most sites with mines. A preliminary evaluation of the explosives contained in the soil was also performed. It showed a concentration of explosives below the detection limit of the prototype (0.8 ppb w/w TNT and below 7.4 ppb w/w for RDX). Higher concentrations in the soil were determined in this minefield in 1997 and 1998 and they showed increased concentration with time. These complementary results have been published in an additional DREV report. Higher concentrations of explosives in the soils should also be present in the cases of an activated mine (with the fuze) in warmer and dryer weather conditions. These favourable conditions may be encountered in many countries with buried mines. However, for security purposes, we have not performed experiments with activated landmines in such conditions.
